Unit Explanations
HertzHz
Source UnitThe hertz (Hz) is the standard unit of frequency in the International System of Units (SI), representing the number of cycles of a periodic phenomenon occurring in one second. It is defined as one cycle per second and is utilized to quantify oscillations, waves, and repetitive events in various fields, including physics, engineering, and telecommunications. The hertz encompasses a wide range of frequencies, from extremely low frequencies in the audible spectrum to extremely high frequencies in radio and microwave domains. The unit is named after Heinrich Hertz, a German physicist who made significant contributions to the study of electromagnetic waves. His pioneering experiments in the late 19th century led to the foundational understanding of wireless communication, making the hertz a pivotal unit in both theoretical and applied physics.
Current Use
The hertz is widely utilized across various industries, including telecommunications, audio engineering, and medical equipment. In telecommunications, frequencies are crucial for the transmission of data and signals, with radio frequencies ranging from 3 kHz to 300 GHz being used for broadcasting and wireless communication. In audio engineering, sound frequencies are measured in hertz, with the human auditory range typically between 20 Hz and 20 kHz, impacting music production and sound design. Additionally, in medical imaging, techniques such as MRI utilize radio frequency signals measured in hertz to create detailed images of the body. Countries around the world, including the United States, Germany, and Japan, employ the hertz in various applications, ensuring uniformity in frequency measurements essential for technology and scientific research.
Fun Fact
The hertz is named after Heinrich Hertz, who was the first to conclusively prove the existence of electromagnetic waves.
CentihertzcHz
Target UnitA centihertz (cHz) is a unit of frequency that is equal to 0.01 hertz, which measures cycles per second. It is a derived metric in the International System of Units (SI) and is used to quantify events that occur in a periodic manner. In essence, 1 cHz indicates that an event occurs once every 100 seconds. This unit is particularly applicable in specific scientific fields and engineering applications where very low frequencies are considered. While it is not commonly used in everyday contexts, the centihertz provides a finer granularity for measurements in phenomena that occur infrequently. For instance, in seismology, the use of cHz can help in analyzing low-frequency seismic waves that contribute to understanding earth movements.
Current Use
The centihertz is primarily used in specialized scientific applications, including geophysics, acoustics, and audio engineering. In seismology, for example, the measurement of low-frequency seismic waves is crucial for understanding earthquakes and tectonic movements, where frequencies in the range of centihertz are often encountered. In acoustics, centihertz can describe the frequencies of sound waves that are below the audible range for humans, significant for research in infrasonic phenomena. Certain telecommunications systems also utilize the centihertz to analyze signal characteristics, particularly in low-frequency transmissions. Although its usage is limited compared to hertz, the centihertz serves as a useful tool in niche markets where precision frequency measurements are required.
Fun Fact
The centihertz allows for the measurement of frequencies that occur once every 100 seconds.

His pioneering experiments in the late 19th century led to the foundational understanding of wireless communication, making the hertz a pivotal unit in both theoretical and applied physics.
History & Origin
The concept of frequency has been recognized since the early studies of harmonic motion and waves. The term 'hertz' was adopted in the late 19th century after the work of Heinrich Hertz, who first conclusively demonstrated the existence of electromagnetic waves in 1887. Hertz's experiments validated James Clerk Maxwell's electromagnetic theory, which predicted that light and radio waves travel as oscillating electric and magnetic fields. The significance of Hertz’s work led to the establishment of the hertz as a unit of measurement for frequency in the 1930s, formalized by the International Electrotechnical Commission (IEC) in 1930 and further recognized by the General Conference on Weights and Measures (CGPM) in 1960.
Etymology: The term 'hertz' is derived from the last name of Heinrich Hertz, which was adopted as a unit of measurement in honor of his contributions to electromagnetism.

History & Origin
The concept of measuring frequency dates back to the work of early physicists and engineers who sought to quantify periodic phenomena. The hertz (Hz), named after Heinrich Hertz in the late 19th century, served as a foundation for defining smaller units like the centihertz. The introduction of the centihertz as a subunit occurred during the standardization of measurement units in the 20th century, particularly with the SI units established in 1960. Its adoption reflects the growing need to measure and analyze frequencies across various scientific domains, including acoustics and telecommunications, where even minute differences in frequency can have significant implications.
Etymology: The term 'centihertz' is derived from the prefix 'centi-', which means one hundredth, combined with 'hertz', the SI unit of frequency.
